Why not? That's what everyone else does. There's not a single admin looking into ban evasion so it's futile (or looking into anything else for that matter). You could have one hundred accounts banned and evade it on your 1000 others and the admins won't look into it. Rules are pointless when they're not enforced. Might as well just let people copy and paste since nobody cares about doing anything about it and if it wasn't for me and rickbig I doubt anyone would do that at all.
